代码生成deepzoom图片集合:安装deep zoom composer
新建一silvlight工程同web一应用一起生成
silverlight工程中MainPage.xaml文件中添加代码如下
<MultiScaleImage x:Name="MyMSI" Source="/test001/output.xml" ImageOpenSucceeded="MyMSI_ImageOpenSucceeded"> <MultiScaleImage.Projection> <PlaneProjection RotationY="10"></PlaneProjection> </MultiScaleImage.Projection> <i:Interaction.Behaviors> <local:DeepZoomInitializer/> </i:Interaction.Behaviors> </MultiScaleImage>
xaml中调用的DeepZoomInitializer类代码如下：此类是用来控制鼠标滚轴的动作

MainPage.xaml.cs中的事件代码：此代码是用来控制多图片显示是出现叠加的问题
private void msi_ImageOpenSucceeded(object sender, RoutedEventArgs e) { var x = 0.0; var y = 0.0; foreach (MultiScaleSubImage subImage in msi.SubImages) { subImage.ViewportWidth = 5.333; subImage.ViewportOrigin = new Point(-x, -y); x += 1; if (x >= 5) { y += 0.6; x = 0.1; } } msi.ViewportWidth = 1; }
deepzoom代码生成代码:单张图片生成代码
private void createimages(string imagename) { SparseImageCreator ic = new SparseImageCreator(); ic.TileFormat = ImageFormat.Jpg; ic.ImageQuality = 1;//0.95; ic.TileOverlap = 0; Microsoft.DeepZoomTools.Image img = new Microsoft.DeepZoomTools.Image(Server.MapPath("~/Files/") + imagename); List<Microsoft.DeepZoomTools.Image> images = new List<Microsoft.DeepZoomTools.Image>() { img }; ic.Create(images, Server.MapPath("~/ClientBin/"+imagename.Split('.')[0]+"/dzc_output")); }
多张图片生成代码：
public void tast() { string source = Server.MapPath("~/Files/"); string dest = Server.MapPath("~/ClientBin/mappimgs"); List<string> images = GetImagesInDirectory(source); List<string> data = new List<string>(); foreach (var image in images) { ImageCreator ic = new ImageCreator(); ic.TileSize = 128; ic.TileFormat = ImageFormat.Jpg; ic.ImageQuality = 0.95; ic.TileOverlap = 0; string target = dest + "/output_images/" + Path.GetFileNameWithoutExtension(image); ic.Create(image, target); data.Add(Path.ChangeExtension(target, ".xml")); } CollectionCreator cc = new CollectionCreator(); Microsoft.DeepZoomTools.Image reqst = new Microsoft.DeepZoomTools.Image(""); cc.TileOverlap = 0; cc.TileSize = 128; cc.TileFormat = ImageFormat.Jpg; cc.MaxLevel = 2; cc.ImageQuality = 0.95; cc.Create(data, dest + "\\output"); } private static List<string> GetImagesInDirectory(string path) { return GetImagesInDirectory(new DirectoryInfo(path)); } //循环出文件中的图片 private static List<string> GetImagesInDirectory(DirectoryInfo di) { List<string> images = new List<string>(); // get all the images in this directory first foreach (var fi in di.GetFiles("*.jpg")) { images.Add(fi.FullName); } // get all the directories with their images foreach (var sub in di.GetDirectories()) { images.AddRange(GetImagesInDirectory(sub)); } return images; }
